RDMA Setup Research Assistances

RDMA Setup Research Assistances

[Michael Tang]

Hello, 

I hope this message finds someone who can potentially help me. My name is Michael, and I’m a computer science student at the University of Colorado - Boulder. I’m researching RDMA, and I’m trying to install and run an example program found on the rdma-core repository hosted on your git. I’m running into some difficulties with just setting up RDMA, and knowledge of how to resolve these issues remain sparse online. I presume the hardware is set up correctly, for I have two Microsoft Azure instances with RDMA capabilities so I just need some advice with the software side. I’m wondering if this email address is an appropriate communication channel to ask for assistance or if I can be directed to some place where I can get assistant. 

Best,
Michael
